DISINFECTING DISPENSING APPARATUS Filed Jan. 16, 1934 2 Sheets-Sheet 2 BY m A ATTORNEYS.

Patented Mar. 30, 1937 UNITED STATES PATENT OFFICE 9 Claims.

This invention relates to an apparatus for dispensing a disinfecting liquid; and has for one of its objects the provision of such an apparatus which may be controlled in its dispensing of the 5 liquid by the flushing of a water closet.

Another object of the invention is the provision of a disinfecting apparatus which is so arranged that it gradually dispenses a disinfecting liquid after being actuated by the flushing of a water l closet.

Another object of the invention is the provision of a dispensing device which may be adjusted to dispense Varying amounts of liquid upon each actuation of the water closet and to dispense the liquid in a varying manner with respect to time.

A further object of the invention is the provision of an apparatus which altho connected to dispense the disinfecting liquid into the bowl oi a lavatory, will also permit evaporation lof some of its liquid into the surrounding air in the room in which it is located irrespective of actuation for discharging its liquid into the lavatory.

A still further object of the invention is the provision of an apparatus so arranged that there can be no intercommunication between the ilow of water which actuates the device and the deodorant or disinfecting liquid which is used for disinecting purposes.

With these and other objects in View, the invention consists of certain novel features of construction, as will be more fully described, and particularly pointed out in the appended claims.

- Y In public toilets where water closets are present, it is desirable to dispense some disinfecting liquid, both into the bowl of the water closet and also into the surrounding air of the roomin which the` water closet is located; and in order that this (Cl. vll-224) may be done in a practical manner and the disinfecting material dispensed into the water closet in proportion tothe use of the water closet, I have arranged to provide for dispensing a certain quantity of my disinfecting` liquid each time the water closet is flushed, whereby I am enabled to cause a container or supply bottle of disinfecting liquidto serve the useful purpose desired and yet use a considerably less quantity than where a container is used which causes continual dropping of the disinfecting liquid; and the following is a more detailed description of the present embodiment of this invention illustrating the preferred means by which these advantageous results Vmay be accomplished:

With reference to the drawings, I0 designates a water closet which is supplied with water thru a conduit II controlled by a valve I2 operated by a handle I3. My disinfecting apparatus is designated generally I4 and is mounted upon a wall I5` adjacent the water closet I0.

This disinfecting apparatusv in one practical embodiment consists of a base I6 comprising a plate I'I with edge flanges I8 tospace it from the wall on which it is mounted. 'This plate is usually of a cast or pressed construction and recessed at I9 for the reception of a wall 20 of the reservoir 2| which is secured in the recess I9 by a bolt 22 extending thru registering openings in the wall 20 of the reservoir and the plate I l. The wall 20 is of an irregular shape which fits the recess and thus-cannot swing about the bolt 22 as a pivot.

The reservoir 2I is of cast or pressed construction and is provided in one corner with a block 23vprovided with bores 25 and 26. There is also a'pedestal 21 cast on the bottom Wall 28 of the reservoir 2l, which pedestal hasV a supporting shoulder 29 for the edge of the neck of a supply bottle or container 3B" which is inver-ted with its edge resting upon the supporting surface 29 of the pedestal 2l, while there extends into the neck of? the bottle a projection 3l' serving as av guide and positioning member and cut away as at 32 in several different locations about itsA circumference for the' discharge of the .disinfecting liquid which the supply bottle contains. This liquid will flow from the bottle when positioned in inverted position on the pedestal 2-1 and iill the reservoir, as illustrated in Fig. 2 at 33, until-,a levelY isA reached, substantially the level of the supporting surface 29 when the opening from `the bottle will be sealed inby its own liquid discharge and as no further air cani enter the atmospheric pressure will' preventfurth'er discharge of the dis- ,55

. infecting liquid. This is referred to as afounV tain feed in connection with this application.

The upper end of the bottle 39 is maintained in desired position by aspring clamp 34 which r"consists of a length of wireV embracing the front,`

of the bottlepand extending along either side with a spring loop 35m either side andV thence thru slots 36 in the base to be turned at right angles as at 31, to maintain the spring clamp 34 in its desired position. By reason of the looseness or t of the clamp and its spring coils on the side, I may lift the clamp over the upper end of the bottle for removing the bottle from position and replacing a fresh one.

In order that the apparatus which I have described may be inclosed, I provide a coverllA which has a tongue 4I to extend thru a slot 42 Y in the base where it is turned ras at 43 to retain it against movement at right angles to the base. Y On the upper end of this cover is provided a tongue 44 to extend thru a slot 44 in thebase and which tongue is notched as at 45 to receive a iinger 45 provided on one end of the `lever 41 which is pivoted as at 48 and moved into locking position bythe opposite weighted end 49. An opening ,50 is provided in the side wall of the base I6 adjacent to the weighted end of the lever 41 thru which opening a pin or the like may be inserted to engage and move the weighted end upwardly, thereby moving the finger 46 of the opposite end downwardly and out of engagement with the notch in the tongue 44' which unlocks and permits the cover to .be removed. YThe base is secured to the wally `I5 Abymeans of the screw r 48 which also serves vas a pivotfor the lever 41 and by means of th'e'additional screws 5I. 'The opening 56 inthe base provides accessfto the pivoted lever when the base is in secured position on the wall. q.

In the bore 52, I have provided a threaded sleeve 53 to engage similar threads 54, while the outer end of the sleeve is threaded as at'55 to may be enlarged by a flaring of the bore 52.

' an opening 6|.V

From the bore 52, ,there extends a conduit 60 to a point in the bowl of the water closet with its open end in a position so that 'when the closet is flushed water will ilow intothe conduit 60 and rise in the tube a substantial extent depending on the force thereof altho after this rst iiushing occurs the water may drain from this pipe thru The conduit 6D isconnected to the bore 25 by a thread sleeve62 and a union 63 in the same manner asis the conduit 51 .connected to its bore as above described.V

From the upper end of bore 25 the conduit 60 now designated 6U', is continued to a height greater than the height of the supply bottle and VVfor practical purposes is bent around the bottle to practically frame thev same. This. tube then passes into and across the bottom of the reser- Voir 2l with its end 65 positioned to discharge vinto the chamber 69, the portion of the tube 60' which extends thru the liquid in thereservoir is perforated as at 66 so that it will fill with the disinfecting liquid altho this openingj66 is of such'V a size that the liquid cannot quickly escape therethrough when air pressure is exerted thru tube 60 and 60 on the surface of the liquid therein.

A small protuberance 80 is provided on the bottomy wall 28 of the reservoir 2| to aid in maintaining the tube 69 in proper position.

If we refer to the schematic view of Fig. 6, we Y of the chamber 59. The portion 69 of the tube 60 will have a disinfecting liquid init also substantially to the level of the liquid in the reservoir or this liquid may be slightly higher due to capillary attraction of the liquid being confined in the smaller tube 60. 'Should the water closet I0 be nowrlushed, water will enter the openqendy 68 of the tube 60 with considerable force and with suflicient force to yforce the liquid up the tube 68 to a substantial extent and thus force the air in the tube to apply pressure upon thev liquid in the U-shaped portion 69 of the tube 60V which is located in the liquid 33. The hole 6| is of such small capacity that its action may be more orV lessof an orifice opening and the water cannot be forced. out fast enough but that the waterrwill be forced up the pipe 60. The compression `of the air will in turn force the liquid in portion 69 of the tube 60 out into the chamber 59 tok fill the chamber and allow any excess-to overflow back into the reservoir and join with the liquid 33 therein. A slight amount ofthe liquid will be 'forced through the opening 66 which is desirable jas the opening 66 is in this Way self cleaning.

The liquid in the Achamber 59 after'being filled will start to escape through the packing 58 slowly and trickle down the tube 51, the speed of which will be governed bythe character of the packing at 50 and the angle of the conduit 51 which may be adjusted to acquire the desired feed of the disinfectant to the water closet bowl.

In some instances, it may be desired to provide a diierent form of bottom wall than the packing 50 and for this purpose I haveprovided a plug 1D with a small opening 1I therein, which plug is positioned in the threaded end 12 of the bore 26 and by adjusting the depth to which the plug 10 is screwed the capacity of the chamber 59 may be regulated and byv using plugs Vof various openings 1 I the rate of `flow may be regulated.

In other instances as I have illustrated in Fig. 9, a cup 15 which may be frictionally placed in the bore 26 and provided with an opening 16 in its bottom wall while there is a bar'11 extending Vacross its mouth for engagement to position it to different depths in the bore V26 for varying the capacity of chamber 59, while I may use cupsY By this arrangement a very compact Acon` trolled dispensing disinfecting apparatus is provided which maybe readily attached and the disinfecting liquid replenished as desired.

The foregoing description is directedsolely A. towards the construction illustrated'but .I desire p it to be understood that I reserve the privilege of resorting to all the `lmechanical changes .to which the device is susceptible, theinvention being defined and limited onlyv by the terms ofthe appended claims.
